Zinc is an essential element involved in a myriad of enzyme systems including wound healing, immune function, and fetal development. Zinc measurements are used to detect and monitor industrial, dietary, and accidental exposure to zinc.
Zinc is an essential component in cellular processes such as DNA replication + transcription. Zinc is also a co-factor from over 300 enzymes. Over 25% of the world's population has a low or marginal zinc status (these symptoms can be mild). Some include loss of appetite/taste or increased susceptibility to infection.
